Abstract:
... In this study, we compared the incidence of postharvest disease and the storage potential of blueberry fruit treated with thymol (inoculated with Aspergillus niger) with those in the control fruit during storage for 42 d at 2 °C. Treatment with 10–30 mg/L thymol was found to be more effective than treatment with higher thymol concentrations of 40–50 mg/L in terms of controlling Aspergillus niger-i ...
... The growth-promoting ability with the organic fertilizers especially humic substance-based products, it has caused their use to be considered. This research aimed to investigate the effect of foliar application of humic and fulvic acids on essential oil compositions and antioxidant activity of yarrow (Achillea millefolium L.) based on Principal Component Analysis (PCA) and calculating the selectio ...

Abstract:
... A novel analytical method using voltammetric second-order modeling based on multivariate curve resolution-alternating least-square (MCR-ALS) is presented for the first time for the quantitation of carvacrol (CAR) in oregano essential oils (OEO). The second-order cyclic voltammetry data were generated on the basis that CAR shows a diffusional system. Thus, the scan rate (v) was used as a second ins ...

Abstract:
... “Empty” V-type starch is a potential carrier for versatile applications in novel ways. This study provided a facile and efficient preparation method of excellent “empty” V-type starch, in which the ordered structure of the carrier was regulated by the complexation temperature without additional annealing treatment. Thymol was used as a model guest material to examine the relationship between the c ...
thymol, etc ; antioxidants; chitosan; encapsulation; tensile strength; thermal stability; Show all 6 Subjects
Abstract:
... Chitosan (CS) is becoming increasingly popular in food packaging due to its natural degradability and great film-forming properties. Nevertheless, its poor antibacterial properties and inadequate antioxidant properties prevent it from being used effectively. In this study, β-cyclodextrin-epichlorohydrin (β-CD-EP) oligomers were prepared and encapsulated with natural essential oils cinnamaldehyde a ...

Abstract:
... An effective and simple surfactant-mediated microextraction of synthetic dyes from solid-phase food samples into the primary amine-based supramolecular solvents is presented for the first time. The developed procedure involved two stages: (i) an isolation of dyes from a solid-phase food sample into a micellar solution of the primary amine; (ii) a preconcentration of the extracted dyes into the sup ...

Abstract:
... Varroa mites are important honey bee ecto-parasites that have caused disaster to the beekeeping industry in Europe and America. The extent of spread of these mites in Africa is not clearly known, but several sub-Saharan African countries including Uganda have been on the varroa-suspect list. We surveyed 16 districts falling in eight agroecological zones in Uganda with the aim of establishing the p ...
thymol, etc ; Apis; Varroa destructor; Xenopus; acaricides; bees; mites; oocytes; parasites; physiology; Show all 10 Subjects
Abstract:
... A major contributor to bee colony decline is infestation with its most devastating pest, the mite Varroa destructor. To control these mites, thymol is often used, although how it achieves this is not understood. One well-documented action of thymol is to modulate GABA-activated ion channels, which includes insect RDL receptors, a known insecticidal target. Here we have cloned two Varroa RDL subuni ...

Abstract:
... Terpenoids are natural compounds originating from five-carbon isoprene units. Over 60,000 terpenoid structures have been identified, and they contribute to the flavor, color, growth, and development of plants. There are several reports on various physiological activities of terpenoids, such as antioxidative and anticancer activities. This study revealed that combinations of terpenoids have activit ...

Abstract:
... There are still many limitations in the application of natural active compounds in meat preservation. Herein, thymol was first inserted into the cavity of β-cyclodextrin (β-CD) to form a stable inclusion complex (THY/β-CD-IC). The computational investigation showed that the optimized complexation energy for THY/β-CD-IC was −12.95 kcal mol⁻¹. It contributed to the improvement of the thermal stabili ...

Abstract:
... The cattle tick Rhipicephalus microplus is one of the most important ectoparasites in the tropical and subtropical regions of the world. Synthetic pyrethroids are widely used to control this tick, and the selection of resistant populations is a huge problem worldwide. The activity of thymol, a natural monoterpene, free or in combination with other compounds, has been demonstrated against different ...

The objective was to determine whether the inclusion of curcumin and microencapsulated phytogenic (alone or combined) could replace the combination of ionophore and non-ionophore antibiotics in the diet of calves in the initial breeding phase and maintain zootechnical performance. The microencapsulated phytogenic blend used in this study contained carvacrol, cinnamaldehyde, and thymol. Twenty-four ...

Abstract:
... Acinos is a small genus of economically important plants belonging to Lamiaceae family whose botanical collocation is quite problematic due to the disagreement among the botanists and the presence in literature of several names and synonyms from different sources.

Abstract:
... Thymol and carvacrol are terpenes which have great potential to be used as preservatives in food and antimicrobial agents in medicinal herbs. As they present low water solubility and display acid-basic properties, inclusion in cyclodextrins and pH variations may enhance their properties. Here, the inclusion of thymol and carvacrol in β-cyclodextrin, at neutral and basic pH at 25 °C, is reported. T ...
... The present study proposes a green extraction approach for the recovery of lycopene from tomato fruits. Different hydrophobic natural deep eutectic solvents (HNADESs) based on terpenes (i.e., menthol and thymol) and fatty acids (i.e., decanoic acid and dodecanoic acid) were prepared at different molar ratios, characterised in terms of density, rheological properties, and Fourier transform-infrared ...
